PROBLEM TO BE SOLVED: To provide an efflorescence generation test method of a cement- hardened body, which is capable of generating efflorescence in a short time. SOLUTION: In this efflorescence generation test method, a cement hardened body is humidified at the temperature of 40-100 deg.C and at the relative humidity of 80-100%, and then cooled spontaneously in one or more cycle at the lower temperature by 20 deg.C or more, than that at the humidifying at the temperature of 0-40 deg.C, and then after spraying 1-100 l/m2 of water on the surface, the body is dried at the temperature of 0-60 deg.C and at the relative humidity below 70%.
